Introduction to intertwined roots: "Plate roots" are an ecological phenomenon. In order to obtain sufficient sunlight, rain and dew, and to support their tall bodies, some trees have developed particularly large wing-like roots at the roots of the trees. In the tropical rainforest, the four trees, Terminalia purpurea, have the most developed plate-like roots. Among the scenic spots with root phenomenon in the developed rainforest scenic spots are "Daiwen Tree, Mountain God's Throne" and so on.
